Normal cells show a property by virtue of which contact with other cells inhibits their uncontrolled growth. This property is known as

Options

A. Metastasis
B. Contact inhibition
C. Proliferation
D. Auto immunity

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about a property of normal cells that inhibits their uncontrolled growth when they come into contact with each other.

2. **Identifying Cell Behavior**: Normal cells exhibit controlled growth patterns. This means that their growth and multiplication are regulated, and they do not grow uncontrollably.

3. **Role of Cell Contact**: When normal cells are in contact with one another, this contact plays a crucial role in regulating their growth. The presence of neighboring cells sends signals that inhibit excessive growth.

4. **Defining the Property**: The property that allows normal cells to inhibit their uncontrolled growth through contact with other cells is known as **Contact Inhibition**.

5. **Differentiating from Other Terms**:
- **Metastasis** refers to the spread of cancer cells to other parts of the body, which is not relevant to the question.
- **Proliferation** refers to the process of cell division and growth, which does not specifically address the inhibition of growth.
- **Autoimmunity** involves the immune system attacking the body’s own cells, which is unrelated to the context of cell growth.

6. **Conclusion**: Therefore, the correct answer to the question is **Contact Inhibition**.
